Title: Improvements in or relating to brake valves
IPC: B60T15/04
Filed: 1958-03-12
Abstract: 887,580. Compressed air brake valves. BEKA SAINT AUBIN A.G. March 12, 1958 [March 13, 1957], No. 7926/58. Class 103 (1). A compressed air brake valve includes a feed valve 8 operable by a piston 11 of a vent valve, the seat 17 of which is moved by piston 11 against spring 24 in the direction of opening of valve 8, a stop 25 limiting opposite movement of seat 17, a spring 22 closing valve 8 against the feed pressure so that the operating resistance of the valve increases on decrease of the feed pressure. The valve housing 1 contains two identical valves controlling independent braking systems and operated by a foot pedal 32 which depresses, through pivot 31 and lever 30, plungers 29 and 29<SP>1</SP> to compress a spring 27 through member 28, and move piston 11 against its seat 17; the seating of piston 11 closes the communication of brake cylinder 13 to atmosphere through port 14, chambers 15 and 16 and passage 19; further movement of the piston with its seat 17 opens, through piston extension 9, valve 8 to admit compressed air from reservoir 5 through port 14 to brake cylinder 5, air also passing through passage 15 to chamber 16 to react on piston 11 to give the operator " feel." On release of pressure on pedal 32, the valve 8 is closed by spring 22. Should pressure in reservoirs 5, 5<SP>1</SP> differ then the valve 8 in the system having the greater pressure will be easier to open and those brakes will be applied first. In an emergency the pedal 32 pivoted to valve housing 1 at 33 is depressed rapidly, the member 28 abutting on stop 26 in piston 11 to rapidly move the piston to open valve 8. Adjustable screws 34 and 34<SP>1</SP> on pedal 32 limit the inclination of pedal 32 to the valve housing 1.

Abstract: 550,949. Combing machines. NASMITH, J. W. June 26, 1941, No. 8011. [Class 120 (i)] Manually releasable means are provided so that when a combing machine of the rectilinear type is stopped, the spring pressure upon the upper jaw of each of the grippers can be relieved and the jaws opened and maintained in the opened position. In one form, Fig. 1, the spring 17 which normally holds the jaws closed, is secured to a hand lever 19 having a pivoted catch member 21 engaging a shoulder 22 upon the framing 14 of the machine. In operation, as the jaws 3, 5 move backwardly, and the vertical arm of a lever 12 linked to the upper jaw 3 moves away from a stop 24, pressure of the spring 17 holds the jaws closed. Upon release of the catch 21, the spring 17 is released, the hand lever 19 moving in clockwise direction to open the jaws. In another form, Fig. 3, a compression spring 17 is arranged between the arm 4 carrying the upper jaw 3 and a swivel member 15 carried in the lower end of a lever 28 which abuts against a lever 26 forming part of the comb-operating mechanism. A catch 21, hinged to the lever 26, engages a shoulder 22 on the lever 28 so that the swivel 15 is so positioned that the spring 17 compresses the jaw 3. Upon release of the catch 21, when the machine is stopped, the lever 28 can be swung clockwise to move the swivel 15 to the position shown in broken lines in which the spring is inoperative upon the jaw 3.

Abstract: 770,658. Machines for moulding concrete &c. blocks. PECK, A. W., and LEE, G. A. March 22, 1955 [March 22, 1954], No. 8272/54. Class 87(2). A machine for producing building or paving blocks or bricks intermittently feeds moulds past a hopper containing breeze, concrete or other material and includes a reciprocable tamping plate and means for synchronizing the feed and tamping plate movements so that the tamping plate effects a compressive and wiping action on the material in the mould during interruption of the feed but is separated from the material during the mould feeding movement. The moulds are formed between successive carrier units b each with a vertical plate b<SP>1</SP> and movable between side plates p which may have shaping ribs p<SP>1</SP>. Each carrier unit has a latch o and a succession of units can therefore be connected. The carrier units, and thus the moulds are moved under a hopper d and tamping plate i<SP>1</SP> for which purpose they have underneath them teeth g engageable by pawls h. On a driven shaft i<SP>1</SP> is an eccentric i2 which causes the tamping plate i to rise and fall. The movement of the tamping plate is communicated to the pawl h on each side by a doubleended lever pivoted to the framework at its mid-point and connected at one extremity to the tamping plate and at its other extremity to a link h<SP>1</SP>, this connection giving the required movement of the tamping plate in relation to the feed. A plate d<SP>1</SP> limits the amount of moulding material remaining in each mould. The position of the plate is adjustable and it is spring-mounted to obviate damage caused by lumps of material becoming jammed between it and the tops of the plates b<SP>1</SP>. Additional vertical plates may be fitted for moulding smaller objects, such as bricks, in which case several tamping plates may be operated from one eccentric. The carrier units are removed as they emerge with the finished blocks, which are taken out on their pallets c, and the carrier units are returned to the input end of the machine and equipped with new pallets.
